MODES FOR THE INVENTION
[0060] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings, but the present invention is not limited or restricted to the embodiments. For reference, in the description, like reference numerals substantially refer to like elements, which may be described by citing contents disclosed in other drawings under such a rule and contents determined to be apparent to those skilled in the art or repeated may be omitted.
[0061]
[0062] Referring to
[0063] In a building, the load may be compressed through walls, foundations, etc. to be transmitted to the bedrock corresponding to the ground. Accordingly, the seismic isolation structure is provided below of the building and separately isolates the base 110 and the support 120, and at the same time, may prevent the shock of the earthquake and the like from the ground from being transmitted to the support 120 and the building thereon.
[0064] The base 110 may be positioned on the ground, and may include an accommodating space 130 with an opened upper portion and two or more rope supporters 112 spaced apart around an entrance 132 of the accommodating space 130.
[0065] The base 110 and the support 120 may be formed by using reinforced concrete, steel framed concrete, durable steel frame, special high-strength alloy, graphene synthetic plastic containing a special alloy, graphene synthetic plastic, carbon fiber, carbon nanotube, graphene, and the like.
[0066] The support 120 may include a stage 122 for supporting an object, a column 124 protruding downward from the stage 122 and positioned in the accommodation space 130, and a flange 126 formed below the column 124.
[0067] The stage 122 may support a building or a column, or other support structures, and may also include a separate fastening structure. The stage 122 may be provided in the form of a dumbbell as a whole by the stage 122, the column 124 and the flange 126, and the height may be adjusted to be located at the entrance 132 of the accommodation space 130 on the narrow column 124.
[0068] The flange 126 may have a relatively larger dimension than the column 124, and a lower surface of the flange 126 through which the rope 140 passes may form a gently curved surface.
[0069] In the accommodating space 130 in the base 110, the column 124 and the flange 126 of the support 120 are positioned, but may maintain a spaced state without colliding with the base 110.
[0070] A plurality of rope supporters 112 may be formed on the upper surface of the base 110 around the entrance 132 of the accommodating space 130. Three or more rope supporters 112 may be formed on each side of the entrance 132 of the accommodation space 130 in the shape of a mooring column, and the ropes 140 may form a plurality of rope lines on the side of the support 120 while repeatedly passing through the lower surface of the rope supporter 112 and the flange 126.
[0071] The plurality of ropes 140 or rope lines may effectively distribute the load applied to the support 120, and stably support the support 120 and the object through the tensile force. In the embodiment, it is possible to maintain stable support by positioning the lower surface of the flange 126 below the entrance 132 of the accommodation space 130.
[0072] The rope 140 may be formed of a material having excellent durability, such as a hanger rope, a steel wire, graphene synthetic plastic containing a special alloy, graphene synthetic plastic, carbon fiber, carbon nanotube, graphene, and the like.
[0073] In this specification, the term ‘ground’ may mean exposed from an exterior such as the bedrock, the ground, the building floor, and the like by vibration, shock, shaking, etc. The ‘object’ is an object that is protected from vibration, shock, shaking, and the like transmitted from the ground, and may be defined in various ways without being limited by size or position, such as buildings, bridges, cultural assets, expensive equipment, and works of art. In the embodiment, the ground may be assumed as the bedrock, and the object may be assumed as a building.
[0074] Accordingly, even if the vibration caused by the earthquake is transmitted to the bedrock and the base 110, the building and the support 120 may be supported through the rope 140, but as the rope 140 shakes, the vibration is not transmitted or may be significantly offset.
[0075] Referring to
[0076]
[0077] Referring to
[0078] The base 210 may be positioned on the ground such as the bedrock, may include an accommodating space 230 with an opened upper portion and two or more rope supporters 212 spaced apart around an entrance 232 of the accommodating space 230, and may be provided in a hexahedral skeleton structure in which front, rear, left, and right sides are opened.
[0079] The support 220 may include a stage 222, a column 224 positioned in the accommodation space 230, and a flange 226 formed on the lower portion of the column 224, and may be adjusted in height so that a relatively narrow column 224 is positioned at the entrance 232 of the accommodating space 230 in the stage 222, the column 224, and the flange 226.
[0080] The flange 226 may have a relatively larger dimension than the column 224 so that the ropes 240 are all provided vertically.
[0081] In the accommodating space 230 in the base 210, the column 224 and the flange 226 of the support 220 are positioned, but may maintain a spaced state without colliding with the base 210.
[0082] A plurality of rope supporters 212 are provided on the upper surface of the base 210 around the entrance 232 of the accommodating space 230, and the rope 240 passes through the lower surface of the rope supporter 212 and the flange 226 to form a plurality of rope lines on the side of the support 220. The rope is fixed (227) to the lower surface of the flange 226 so that relative slippage does not occur.
[0083] The plurality of ropes 240 are preferably vertically parallel with each other. To this end, the flange 226 and the boundary of the entrance 232 of the base 210 may be designed to be matched vertically, and rope guide grooves or protrusions are additionally formed on the entrance 232 of the base 210 or the outside of the flange 226 to adjust the dimension so that the ropes are vertical or prevent the ropes from moving unintentionally.
[0084] Two arbitrarily selected from the ropes 240 formed above may be vertically formed with the same length as each other to form two opposite sides forming a rectangle.
[0085] As illustrated in
[0086] When horizontal vibration W such as an earthquake in
[0087] Referring to
[0088] As illustrated in
[0089] In addition, when the support 220 is shaken horizontally, the vertical and vertical movement may also be affected according to the elasticity of the rope. For example, as the elasticity of the rope is less, the vertical vibration may be greatly generated, and as the elasticity is increased, the vertical vibration may be offset. Therefore, in order to reduce the vertical vibration of the support, it is also possible to use a relatively high elastic rope or to add a spring to the rope.
[0090]
[0091] Referring to
[0092] The support 320 may include a stage 322, a column 324 positioned in the accommodating space 330, and a flange 326 formed on the lower portion of the column 324, and the plane thereof may be formed in a rectangular shape rather than a square shape.
[0093] A plurality of rope supporters 312 are provided on the upper surface of the base 310 around the entrance of the accommodating space 330, and since the rope supporter is formed in a rectangular shape, a relatively large number of rope supporters 312 may be formed on the long side. The rope 340 may form a plurality of rope lines on the side of the support 320 while passing through the rope supporter 312 and the lower surface of the flange 326, but the rope 34 may pass through all of the rope supporters 312, and in some cases, the ropes may be concentrated to be locked to some rope supporters 312.
[0094] As listed in
[0095] In addition, when using a rope made of a steel wire, the tensile strength may be formed about 10 times larger than steel of the same thickness. A steel wire with a diameter of about 16 mm may have a cross-sectional area of about 2 cm.sup.2, and since the steel wire may support about 30 tons per 1 cm.sup.2, a steel wire rope with a cross-sectional area of about 2 cm.sup.2 may support about 60 tons.
[0096] If the steel wire ropes are arranged at intervals of about 70 mm to form 56 rope lines, the steel wire ropes may support a total of about 3,360 tons, and if four such seismic isolation structures are disposed at 4 corners of the building, about 13,440 tons of the load of the building may be supported. For reference, the total weight of the Eiffel Tower in Paris is about 7,500 tons.
[0097] Furthermore, considering that the rope using graphene has a tensile strength that is at least 10 times higher than that of a steel wire with the same thickness, a seismic isolation structure using a graphene rope can be applied to buildings that withstand a load of 10 times or more.
[0098]
[0099] Referring to
[0100] In addition, a flange 426 of the support 420 may be provided with a lower rope hanger 427 corresponding to the rope supporter 412. Accordingly, the rope 440 may form a plurality of rope lines connecting the top and bottom while alternately passing through the rope supporter 412 on the base 410 and the lower rope hanger 427 of the flange 426.
[0101] While the ropes in the previous embodiment are connected to the rope supporter on the opposite side via the lower surface of the flange, in the embodiment, the ropes 440 may be formed while reciprocating up and down from one side of the support 420. Therefore, in the embodiment, the four ropes may be separately formed on the front, rear, left, and right sides, respectively.
[0102] The respective ropes 440 may be entangled with each other while reciprocating between the rope supporter 412 and the lower rope hanger 427, and both ends of the rope may be connected to a turnbuckle 442 via the outer rope hanger 414. In this case, it is possible to finely adjust the rope length using the turnbuckle 442. A rope fixing device capable of fixing the corrected rope by the turnbuckle 442 may be further added to the outside of the outer rope hanger 414.
[0103] As illustrated in
[0104] Even in the upper portion of the base 410, guide grooves 416 may be further formed on the inner wall of the entrance of the accommodation space for positioning and vertically aligning the ropes 440.

[0107] Referring to
[0108] The rope 540 may be formed in a flat belt shape, and as illustrated in
[0109]
[0110] Referring to
[0111] A drain 616 may be formed downward of the base 610 so that rainwater or groundwater introduced therein may be discharged to the outside.
[0112]
[0113] Referring to
[0114] The critical shock blocking device 750 may provide resistance to wind pressure, a weak earthquake, or the like while limiting the movement of the support 720 while stretching within a predetermined range. To this end, the critical shock blocking device 750 may include anchors 752 at both ends, a connecter 754 connecting the anchors 752, and a spring 756 mounted between the anchor 752 and the connector 754.
[0115] Accordingly, when a gust of wind, wind pressure, a weak earthquake, or the like is applied, the critical shock blocking device 750 may limit the movement of the support 720. However, when a force greater than or equal to a critical shock such as a high-strength earthquake is applied, a central portion 755 of the connector 754 is flexibly stretched or damaged, so that the support 720 is seismically isolated from the base 710.
[0116] The anchor 752 may be rotatably fixed to the lower surface of the stage 722 of the support 720 and the upper portion of the base 710, and may use a structure such as a ball joint.
[0117] In addition, the anchor 752 may be connected to the connector 754. When the connecter 754 is broken, it is also possible to replace the connecter 754.

[0121] Referring to
[0122] In addition, as illustrated in the drawings, the bedrock and the building are separated by the seismic isolation structure 300. Accordingly, even when shaking W by an earthquake occurs as illustrated in
[0123] It can be seen that the part of the building supported by the support may be kept in a very stable state without being impacted, while the ground connected to the bedrock shakes.

[0135] The tent membrane 140′ may be provided in the form of a membrane or a net, and may be manufactured in various shapes as needed. In addition, the tent membrane 140′ may be formed using graphene synthetic plastic containing a special alloy, graphene synthetic plastic, carbon fiber, carbon nanotube, graphene, etc.
